$vSphereLicenseInfo = @()
$ServiceInstance = Get-View ServiceInstance
Foreach ($LicenseMan in Get-View ($ServiceInstance | Select -First 1).Content.LicenseManager) {
Foreach ($License in ($LicenseMan | Select -ExpandProperty Licenses)) {
$Details = "" |Select VC, Name, Key, Total, Used, ExpirationDate , Information
$Details.VC = ([Uri]$LicenseMan.Client.ServiceUrl).Host
$Details.Name= $License.Name
$Details.Key= $License.LicenseKey
$Details.Total= $License.Total
$Details.Used= $License.Used
$Details.Information= $License.Labels | Select -expand Value
$Details.ExpirationDate = $License.Properties | Where { $_.key -eq "expirationDate" } | Select -ExpandProperty Value
